CAUTION
DO NOT OPERATE THE WINDSHIELD WIPER ON DRY GLASS. THE
WIPER WILL CAUSE DAMAGE TO THE WINDSHIELD. ALWAYS SUPPLY
WATER TO THE WINDSHIELDS BEFORE YOU OPERATE THE WIPER.
(b) Supply a continuous spray of clean water to the windshield.
NOTE: For windshields with a hydrophobic coating, deionized or distilled water is
recommended during the wiper test. Water with a high mineral content can cause
marks on the coated glass surface that are difficult to remove. If water with a high
mineral content is used on a windshield with a hydrophobic coating, flush the
windshield surface after the wiper test with deionized or distilled water, or remove
the remaining water on the windshield with a cotton cloth.
